Work stealing, which is a popular scheduling strategy for task parallel programs, can efficiently perform dynamic load balancing however, it tends to damage data locality and does not scale well with memory-bound applications. With task parallel models, programmers can easily parallelize divide-and-conquer algorithms by using nested fork-join structures. Experiments on an Intel Knights Landing server that adopts bandwidth-asymmetric memory show that BATS reduces the execution time of memory-bound programs up to 83.5% compared with traditional task-stealing schedulers. The hierarchical scheduler improves data locality at runtime without a priori program knowledge. According to data access hotness, the traffic balancer migrates data to balance memory traffic across memory nodes proportional to their bandwidth. SYSMON ONLINEPRO CODELeveraging compile-time code transformation and run-time data distribution, the data allocator enables HBM usage automatically without user interference. To solve the two problems, we propose a Bandwidth and Locality Aware Task-stealing (BATS) system, which consists of an HBM-aware data allocator, a bandwidth-aware traffic balancer, and a hierarchical task-stealing scheduler. ![]() However, existing task schedulers suffer from low bandwidth usage and poor data locality problems in bandwidth-asymmetric memory architectures. Adapter board (only for CAE017332).Parallel computers now start to adopt Bandwidth-Asymmetric Memory architecture that consists of traditional DRAM memory and new High Bandwidth Memory (HBM) for high memory bandwidth.
